How can I debug the post response sent to the AccessTokenURL?

I need to check if the body of that response is well constructed cause I'm having errors there with my custom Provider and I'm not sure where to look. The "debug" flag shows me the URL but not the body of the response.

have you checked the network tab? 🤔

But that one (AccessToken) is a server side request. Isn't it?

Ah, you are right! I'll check out if we can improve logging there as well.

As a workaround, you can try to log params in node_modules here:

next-auth/src/core/lib/oauth/callback.ts

Lines 88 to 99 in 35ee608

	const params: CallbackParamsType = {
	...client.callbackParams({
	url: `http://n?${new URLSearchParams(query)}`,
	// TODO: Ask to allow object to be passed upstream:
	// https://github.com/panva/node-openid-client/blob/3ae206dfc78c02134aa87a07f693052c637cab84/types/index.d.ts#L439
	// @ts-expect-error
	body,
	method,
	}),
	// @ts-expect-error
	...provider.token?.params,
	}
